Question 718288: Solve and graph the solution: x+1 is greater than or equal to 7 and -6x is greater than 24

You can put this solution on YOUR website!
x%2B1+%3E=+7 and -6x+%3E+24
First we solve each inequality. For the first one we just have to subtract 1 from each side. For the second one we divide by -6 and remember to reverse the inequality (because we are dividing by a negative!):
x+%3E=+6 and x+%3C+-4

The "and" between the two inequalities means we are only interested in x values that make both inequalities true. In other words we want x to be greater than or equal to 6 and less than 4 at the same time! With a little thought we should realize that there are no such numbers! It is impossible for a number to be both greater than or equal to 6 and less than 4 at the same time. So there is no solution to this compound inequality. The graph would just be a number line with no dots or shading on it.
